A 66-year-old male patient of renovascular hypertension with nephrotic syndrome was described. Besides, focal segmental glomerulosclerosis like lesion was accompanied in the contralateral kidney. On admission, his blood-pressure amounted to 220/140 mmHg. Laboratory investigation included; urinary protein 10.5 g/day, serum creatinine 1.8 mg/dl, creatinine clearance 71.4/day, plasma renin activity 10.0 ng/ml/hr, angiotensin I 890 pg/ml and angiotensin II 40.0 pg/ml. Renogram and renal scintigram showed non-functioning pattern of left kidney. Arteriography disclosed approximately more than 95% stenosis of left main artery. Administration was discontinued because of poor control both in blood pressure and in proteinuria. After the left nephrectomy, the former normalized and the latter decreased. Microscopic examination of the right kidney revealed focal segmental glomerulosclerosis like lesion. So far as we know, this report is the first designed to elucidate renovascular hypertension with nephrotic syndrome accompanied by focal segmental glomerulosclerosis like lesion. The relationship between renovascular hypertension and nephrotic syndrome, and microscopic findings has been briefly discussed. It is suggested that the etiology of focal segmental glomerulosclerosis like lesion may be based on compensatory glomerular hyperfiltration caused by renovascular hypertension.
